Yugama Crater Lake of Mt. Shirane

As some of you might know I had a great time during my summer vacation. I visited various places, but today I want to share one of my highlights with you: The Yugama Crater Lake of Mt. Shirane

Favorite Photo #4: Crater Lake Yugama

*Click to enlarge

What you see in the photo is one of the three crater lakes of the volcano Mt. Shirane (白根山).
It is a 2160m active volcano in Kusatsu, Gunma Prefecture. It’s called Kusatsu Shirane (草津白根山) to avoid confusion with Mt. Nikko Shirane (日光白根山） on the other side of Gunma Prefecture.

“Yugama” (湯釜, lit.: hot water pot) is the largest of Mt. Shirane’s crater lakes and looks stunning with its turquoise color and with rafts of yellow sulfur floating on its surface. The caldera lake measures 300m in diameter and 30m in depth and the water temperature is approximately 18°C.
Because of its very high acid level of about PH1.0, plants cannot grow around this lake.

You can easily access “Yugama” by bus from Kusatsu’s bus terminal and then hike up for about 20 minutes. It’s an easy hike!

Important visitor’s note:
Hiking is only possible from mid April to early November!

Yugama is a stunning site – a lot more breathtaking than any photo can express!
The nearby Kusatsu Onsen Resort is also totally worth a visit. You can easily do both as a day trip if you are already in Gunma Prefecture.
Stay tuned for my blog post about Kusatsu where I hopefully can show you the real beauty of Kusatsu!

Curious? Hoverover the sushi!

Do you enjoy this website? Great! It would be awesome if you could help to keep it running. It costs a lot of money and effort to keep this website alive! So how about inviting me to some delicious sushi?
Thank you so much!

Ahh, I wanna go to a place like this!! It just looks like such a chill place. I also wonder if that onsen nearby has any special mineral pools from the volcano Ah, this is has to be the coolest looking spot in Japan that I’ve seen ever
